The 49ers strategy is called, "Invest/reward your own players, succeed through draft, and pick up bargain-vets to stop-gap for rookies"
Think of it this way:
1. Yes, we did lose a great safety in Goldson, a vet WR in Moss, solid TE in Delanie, and two strong NT/DE guys in Sopoaga/RJF, but think about this, would you rather have any of those guys than A. Davis, Iupati, Kaep, Crabs, Aldon Smith?
If we signed those guys, we would've lost out on solidifying our #1 ranked OL, a QB star, emerging #1 WR, and a premiere pass rusher.
2. Of the guys we lost, which appears to be unfixable? This draft is deep in DL and TE, so not worried about losing those guys since we do have 14 picks. Safety-wise, is Goldson a 8mil a year player? Yes, Whitner gave up more plays, but didn't see Goldson stepping up either. I wish him well (fellow Husky), but we can get a stop-gap in FA (Woodson most likely) for a 1-year deal.
If not, should move Cully over to FS, which I feel, will become his natural Pro-bowl position.
3. Dahl isn't a starting FS. Did anyone notice we have lost a few ST players? We just snagged two very solid ST standouts from other team in Skuta and Dahl, reminding everyone ST plays win championships (see beginning of 2nd half in SB this year
The only thing I'm worried about is our CB situation. I feel we need more depth and the draft appears more top heavy. I'd like a look @ asomougha, but I have a feeling he wants top-tier money, but he's not getting that from ANYBODY (not even from CB lacking Saints). Think he will be humbled (similar to Goldson two years ago), sign 1 year deal with us, get back to pro-bowl level, and leave for a payday.
Not totally against a Revis trade, but would like it back loaded so to allow us to resign our own guys. Revis on one leg is still better than 75% of the league, and I think he'd LOVE to show off his skills against Sherman.
